professional training, conduct,

jurisdictional/professional codes and
regulations.
Procedure for First Shutdown
The heater system should be shut down after no more than 24 hours of
operation at full operating temperature. At this time, the following maintenance
items will need to be completed to meet warranty conditions.
1. While pump is still at operating temperature, align circulating pump(s) to
pump manufacturer’s specifi cations. This should be done by means of a
dial indicator.
2. Isolate Y-strainer(s) in system and clean regardless of pump suction
pressure. Make sure that the temperature is low enough to handle safely
or provision has been made to handle materials at high temperature.
Generally, temperatures below 150°F (65.5°C) are acceptable to perform
operation with regular work gloves.
3. With piping system cooled to ambient temperature, torque all bolts on
skid and throughout system to gasket manufacturer’s specifi cations using
proper fl ange torquing practices such as incremental torque increases, star
pattern, etc. Refer to torque specifi cations in Tables 6 - 9.
4. Visually inspect all thread fi ttings and valve packings. Repair leaks and
tighten valve packings to the point of stopping leak.
5. Upon putting unit back into operation, check all gauge readings. Note any
discrepancies and contact Fulton.
Daily Start-Up
1. Check positioning of all system valves to ensure fl ow is not dead-headed.
2. Visually check relative position of minimum level fl oat switch in the
combination tank.
3. Turn on power supply switches.
4. Where applicable, open water cooling valve and check that water fl ows
correctly. (For water cooled pumps only.)
5. Set three position switch to “Pump”. Push and hold manual pump start
button, monitoring pressure gauges on heater.
6. When ready to begin heating, move three position switch from “Pump” to
“Heat”. After a short delay resulting from the purge period, the burner will
ignite. Make sure that the temperature setpoint is as desired.
7. On gas units, pilot valve activation will be indicated after pre-purge cycle
has completed, followed by main fl ame activation. Check the presence of
the fl ame by observing fl ame signal strength from fl ame programmer or
testing device. Operator attendance during warm-up is a recommended
precaution.
8. Start-up is considered complete when the unit begins to throttle back or
shutdown on target temperature.
